Hi,
So I have all the components
  • Harmony 880
  • Sony HDTV
  • PS3
  • Onkyo TX-SR607
  • ATT Uverse internet and cable
  • x10 IR extender
  • PS3IR-500 for PS3



My question is how do I setup TV, PS3, and Onkyo for Harmony 880.

I couldn't find a good How-To article anywhere. I tried setting up the TV and Onkyo for "Watch TV" activity but I can't get the PS3. I have Harmony configured in PS3 but when I switch to Game it says no-signal. I have PS3 connected via HDMI to "Game" input, also labeled as IN4.

I have PS3 setup using "Watch a movie" activity for PS3IR-500 device.

Please guide.

Thanks,
Prince
